What the May 2026 Rate Hike, Weak Rand and Rising Costs Mean for South African Small Businesses
On 28 May, the South African Reserve Bank did something it hadn’t done since 2023: it raised the repo rate, taking it to 7%. In an ordinary year that would have been the business story of the month. This year it had company. Inflation had climbed from 3.1% in March to 4% in April, and has since risen further to 4.5% in May. Petrol went up at the start of June even as diesel eased. The rand spent the autumn drifting near R16.50. And anyone who has bought steak recently already knows the punchline there: meat is running roughly 7% higher than a year ago, according to Stats SA.
South African owners are used to absorbing one of these at a time. A fuel reset here, a soft rand there. It’s the normal weather of trading in this country. What’s odd about the current stretch is that everything moved inside about five weeks, and mostly in the same direction. At Merchant Capital we’ve funded small businesses through more than a decade of cycles, and the quarters that do real damage usually look like this one: a pile-up rather than a single dramatic shock. So it’s worth slowing down and taking it apart properly.
What’s driving costs up right now?
Start with the Bank, because its decision came with a warning attached. Alongside the hike, it raised its inflation forecast and flagged what it calls “second-round effects”. That’s central-banker shorthand for a price shock that refuses to stay where it started. Fuel goes up, so delivery goes up, so the wholesaler reprices, so the café’s toasted sandwich quietly gains a few rand. By the time the original shock has worked through the chain, it’s in everything, which is partly how inflation jumped nearly a full percentage point in a single month.
Fuel itself is doing something strange. The June adjustment actually brought relief for diesel users while pushing petrol up sharply, and the revised fuel and slate levies alone account for close to R1.85 a litre of that increase. Behind it sat an oil market rattled by the Iran conflict and the closure of the Strait of Hormuz. That has since eased: a ceasefire reopened the strait, oil fell back from its wartime highs to the mid-$80s, and July brought real relief at the pumps, with petrol down about R2 a litre and diesel by more than R3. These shocks can reverse as fast as they arrive, even if few resolve on a convenient schedule. Then there’s the rand. At around R16.20, still soft by longer-run standards, anything imported gets pricier at the till, and in a small business that covers more than people think: stock, equipment, packaging, the software subscriptions billed in dollars.
What does a 7% repo rate actually mean for your business?
The obvious effect is that variable-rate debt, the overdraft, the vehicle finance, the bond on the premises, costs more from next month. Most coverage stops there. The more interesting effect is the one the hike is designed to have. Raising rates is how a central bank cools spending. The discomfort is the policy.
Which means your customers’ disposable income tightens in the same months your own costs rise. A retailer feels the hike twice, once on the overdraft and once at the till, and the second hit usually matters more. With the Bank signalling further tightening before its next decision on 23 July, waiting to see what happens is itself a decision, and it carries a price like any other.
Why do the same shocks hit smaller businesses harder?
Mostly it comes down to buffers. A large company buys on 30-, 60- or 90-day supplier terms, holds cash reserves and often hedges its currency exposure, so a May shock might only reach its income statement in spring. An independent usually pays upfront or close to it. The fuel increase that takes a listed retailer a quarter to feel reaches a small distributor on the next delivery. Add thinner margins and there’s simply less padding between a price move and the bank balance. The headline number is identical for everyone. The weight of it isn’t.
What do the businesses that come through these stretches actually do?
We’re wary of telling anyone how to run their shop, since every business is its own animal. But after watching thousands of them move through several cycles, some patterns are hard to miss.
The owners who exit a squeeze in decent shape generally know their numbers early, and by numbers we don’t mean turnover. We mean unit economics: which products genuinely make money and which only generate activity. That knowledge changes how they handle price. Rather than a blanket increase across the board, which is the fastest way to unsettle loyal customers, they lift the handful of lines that have stopped paying their way and leave the rest alone.
They’re also stingy in a particular direction. Cutting the things that bring customers back, the quality, the service, the loyalty discount that’s been running for years, saves money this month and costs revenue for the next twelve. The better operators cut around those things rather than through them. Timing shows up too: buying ahead of a known levy change or a busy season beats scrambling in the rush with everyone who left it late. And the ones who handle a quarter like this tend to have funding whose repayments move with their income, easing in quiet months instead of landing as a fixed bill at the worst possible moment. (We sell exactly that kind of funding, so apply whatever discount you like to the observation. The principle holds whoever the lender is.)
A note for the accountants, brokers and consultants
If you advise small business owners, a fair amount of this is landing on your desk right now. The most valuable thing you can do in a stretch like this is help a client sort the temporary from the structural. In the moment everything feels permanent: the rand will never recover, the rate will never come down. Owners make their worst decisions from inside that feeling, and a calm second opinion on what’s a cycle and what’s a trend is worth a great deal more than another forecast.
Where this leaves you
The next date that matters is 23 July, when the Bank decides again. Between now and then, the useful question is less about getting through the month, which most businesses will, and more about what you want your cost base and pricing to look like when the cycle turns. Because it will. The owners who treat a squeeze as a forced audit usually come out of it running a tighter business than the one they took in. That part, at least, is in your hands.
